Product Description

Stainless steel precision tube is a high-precision steel tube material widely used in machinery manufacturing, medical equipment, aerospace, and petrochemical industries. Primarily manufactured from grades like 304 and 316, it offers exceptional corrosion resistance and high strength. The diameter and wall thickness tolerances are strictly controlled, often reaching ±0.05mm or less, ensuring superior quality.

Utilizing both cold drawing and rolling processes, these tubes feature a smooth surface and precise dimensions to meet demanding technical specifications. They are essential for precision instruments, hydraulic systems, and pneumatic systems, while also providing excellent welding performance for versatile industrial applications.
